Porin Insertion in the Outer Mitochondrial Membrane01:12

Porin Insertion in the Outer Mitochondrial Membrane

4.9K
Porins are beta-barrel proteins translocated to the mitochondrial outer membrane through the TOM complex into the intermembrane space. Porin precursors bind TIM chaperones within the intermembrane space and are guided to the Sorting and Assembly Machinery complex or SAM complex on the outer mitochondrial membrane.
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...

Protein Transport to the Outer Chloroplast Membrane01:11

Protein Transport to the Outer Chloroplast Membrane

2.4K
Chloroplast outer membrane proteins encoded by the nucleus are synthesized in the cytosol. Soon after synthesis, they bind cytosolic factors such as 14-3-3 protein and the Hsp70 chaperones that keep these precursors in an unfolded state until their translocation.
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.

Bacterial Transformation01:33

Bacterial Transformation

60.4K
In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

Outer Layers of the Cell Envelope01:18

Outer Layers of the Cell Envelope

1.3K
The outermost layers of prokaryotic cells play a critical role in their survival, virulence, and interaction with the environment. These layers, often composed of polysaccharides, polypeptides, or proteins, form protective and adhesive structures that vary in organization and function.Capsules and Slime LayersCapsules are highly organized, tightly bound layers that firmly attach to the bacterial cell wall. Capsules are usually made of polysaccharides, though some are made of polypeptides. These...

Bacterial Signaling01:30

Bacterial Signaling

41.4K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Introduction to Membrane Proteins01:16

Introduction to Membrane Proteins

81.7K
The cell membrane, or plasma membrane, is an ever-changing landscape. It is described as a fluid mosaic where various macromolecules are embedded in the phospholipid bilayer. Among the macromolecules are proteins. The protein content varies across cell types. For example, mitochondrial inner membranes contain ~76% protein content, while myelin contains ~18% protein content. Individual cells contain many types of membrane proteins—red blood cells contain over 50—and different cell...

Area of Science:

  • Microbiology
  • Cell Biology
  • Biochemistry

Background:

  • Gram-negative bacteria possess an outer membrane acting as a barrier against antibiotics.
  • Antibiotic resistance is amplified by efflux pumps, limiting treatment options.
  • Cell division requires coordinated constriction of the outer membrane, peptidoglycan, and inner membrane.

Purpose of the Study:

  • To review current knowledge on outer membrane constriction during Gram-negative bacterial cell division.
  • To explore the molecular mechanisms synchronizing cell envelope biogenesis during division.
  • To identify potential vulnerabilities for enhancing antibiotic effectiveness.

Main Methods:

  • This review synthesizes existing research on Gram-negative bacterial cell division.
  • It focuses on the coordination of outer membrane, peptidoglycan, and inner membrane biogenesis.
  • Literature search and analysis of molecular mechanisms involved in cell envelope constriction.

Main Results:

  • The precise molecular mechanisms governing outer membrane constriction during cell division are not fully understood.
  • Coordination between the three cell envelope layers is critical for bacterial survival.
  • Disrupting outer membrane integrity can increase antibiotic susceptibility.

Conclusions:

  • Understanding outer membrane biogenesis during cell division is key to combating Gram-negative infections.
  • Exploiting vulnerabilities in this process could lead to novel therapeutic strategies.
  • Further research into the molecular machinery of cell division is warranted.
